The viewer can be found under cse327_ta, in a folder called "1 Point Viewer". To use it, just drag the point file onto the application. Included is Prof. Oliveira's "cow.dat" dataset as an example. The layout of the input file consists of the number of points in the first line followed by the list of points, each represented by its X, Y and Z coordinates plus RGB color. The RGB values are assumed to be in the range [0,1] (black, white). RGB values are used if you want to use color images in the future. Also they could come in handy if you want to display two different datasets simultaneously, you could assign different colors to the points of each dataset. If you want white points enter 1.0 1.0 1.0 for the RGB values. The format of the file: # points =3D ... The program opens three windows. The first is a console, which remains empty. The second is the view pane, where everything is displayed. The third is the control panel, on which you can toggle the axes on and off and switch between moving and rotation. X-axis and Y-axis changes are made with the left mouse button. Z-axis changes are made with the right mouse button. Note that if you zoom in too closely, the image will pass inside of the near clipping plane and disappear. Also note that on machines with poor video systems the green and blue colors of the Y and Z axis indicators will turn the same shade of red as the X axis indicator. To exit the program, either press the Quit button on control panel or close any of the three windows.
